Abstract
In a light ray controller, a light transmission diffusion layer and a light reflection layer are laminated on each other. The light ray controller is arranged such that the light transmission diffusion layer is located between a rotation center axis and the light reflection layer. A light ray generator emits a light ray group including a plurality of light rays towards the light transmission diffusion layer rotated by a rotation module. The light transmission diffusion layer transmits the light ray group while diffusing it in a vertical direction. The light reflection layer reflects the light ray group that has been transmitted through the light transmission diffusion layer. Based on three-dimensional data, the light ray generator is controlled by a control device such that a three-dimensional image is presented by the light ray group that has been reflected by the light reflection layer and transmitted through the light transmission diffusion layer.
